Lucky, this is at least the third trivial problem you asked in recent days.

Programming is the challenge of discovering how to solve a continuous 
series of new problems. If you don't think you would like to do that, 
find something else to do. If you do, go to it.

How I would approach it:

1) Define the problem ACCURATELY - its leading zeroes you want to remove.

2) Find three ways to solve the problem.
   a) Split it up in to its parts, chop off leading zeros, reassemble.
   b) Its a date, so convert to binary date and convert back to 
formatted date using library functions.
   c) Parse it to remove any zero that occurs after a slash.

3) Choose the best, implement it and test it properly.
